BED-SPRING."

SPECIFICATION forming part of Letters Tl-"atent No. 224,315, dated February 10, 1880..

Application filed May 9, 1879. i

To all whom it may concern:

Be it known that I, LA FAYETTE WILDER- MUTH, of New Lexington, in the county of Perry and State of Ohio, have invented new and'lmproved Bed-Springs; and I herebyrdeclare the followin g to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of Y this specification, in which- Figure 1 shows a single spring with my im-v spring on which straw and other beds will rest- .with equal facility and comfort as with a mattress 0r upholstered bed. p My invention consists in providing the coiled spring with an end projecting from the coil proper and bentin a peculiar S. shape with one abrupt bend, and bending the extreme end into a hook to engage in an adjacent spring in the coil next below the top coil, as hereinafter more fully described and claimed.

In the accompanying drawings, A represents an inverted cone-shaped wire-coil spring,

having proper devices a b at its lower end to clasp the bed-slat. When this spring is made the upper end of the wire is left projecting to a considerable distance, and is subsequently bent in" a reverse curve at d,,and brought around about two-thirds of a circle of somewhat less diameter than. the top coil of the spring. Then, at e, thewireis bent abruptly and runs straight in a line through the centers of coiled spring A and'reverse bend d,

terminating in ahook-bend, h. From thebend 3 eto the hook h the wire lies beneath the reverse-curve bend at d. These springs have they will be in a diagonal line to the slat when the claspa b seizes it, and they are long enough to reach the next alternate spring on the adjacent slat'and hook onto its coil next tothe top coil, as seen at s s,Fig. 4. The springs are hooked together in the manner shown in Fig. 4 to make up the bedi-frame, leaving diagonal lines of springs hooked together. V

I have found by actual experiment that a series of springs constructed as described and shown and set up in the manner marked out will sustain not only mattresses, but straw and other/beds to an equaladvantage.

it is quite evident that duplex springs made with my invention may be used in the same manner without departing from the spirit of my invention. '(See modifications shown in Figs. 2 and 3.)

I do not desire to be understood as claiming, broadly, extending the end of a coiled spring to the coil of an adjoining spring, nor connecting the coils of springs together, nor connecting the coils of duplex springs together at the bottom with a wire having irregular bends for the purpose of adjustment, as I am aware that they are old; but,

Having thus described my invention, what. I claim as new,and desire to secure. by Letters Patent, is-

The herein-described bed-spring, provided with a projecting end having a reverse curve at d, bent abruptly at e, and running straight in a line through the centers of coiled spring and below thereverse curve cl, and terminating in a hook-bend, h, substantially as and for .the purpose specified.
